2-in-1 fun – Build the first flip vehicle in LEGO® Technic™ history with this LEGO Technic App-Controlled Transformation Vehicle (42140) set, featuring a tracked racer and tracked exploration vehicle

See the model flip! – The vehicle flips over when it hits a wall or can be flipped by hand to reveal the brightly colored tracked racer on one side and an orange exploration truck on the other side
